Jet, thank-you so much for your response, you inadvertently hit a number of key points for me with your reply.
I have some 500 Barnes 250gn T.S.X's in store for my rifle and have battled getting a good load for them (some of that involved issues I was having with my chronograph at the time).
69gns of R 15 proved to be a little on the warm side for my gun which is a 1909 Argentine Mauser, and at the time of testing only gave some 2600fps, (an unreliable read from a faulty chrony, which I didn't know at the time).
I will be re-testing loads with R 15 and will start somewhere around the 63gn mark and work up from there.
I am very happy to hear of your findings of terminal results with the T.S.X's.
Very impressive, and what I would expect of a projectile I have been using in other calibers on large game.
Personally, I've always preferred pass throughs giving an entry AND an exit, to projectiles that mushroom under the skin on the far side.
I have used the 300gn T.S.X in .375 extensively on buffalo and Wild Oxen here in Aus with effective, reliable and repeatable results.
Having recently made the move over to 9.3 caliber I was hoping that the T.S.X's would be as reliable as they are in .375.
It is great to hear of the tremendous damage they are doing in your rifle on moose, bear and sheep as I too intend to employ this gun on "lesser" game such as deer and had a concern in the back of my mind of the T.S.X's penciling through with little damage.
That concern is now put to rest, thank-you.
Concerning your trials with other projectiles I am glad to see you are open to testing new tech and are trying the C.E.B's.
I have used, and seen used, several hundred on buffalo (and other game) and can assure you; you are in for a treat !
In your Win M70 you will get away with the 250gn Raptor which will have no problems feeding through the cone breech system of a Winchester but you may struggle getting it to feed in the Schonauer and you may need to step down to the 210gn Raptor which is shorter.
I would be interested in hearing of your impressions and results of your use of this projectile and general info on the 9.3x64.

Thank-you again for sharing your experience and knowledge, very much appreciated.
